PI74AUC164245
16-Bit 0.8V to 2.7V Scaled Configurable Level
Shifting Transceiver with 3-State Outputs
Features
Description
• PI74AUC164245 is designed for low voltage operation:
0.8V to 2.7V
PericomSemiconductor’sAUCseriesof logiccircuitsareproduced
using the Company’s advanced CMOS technology, achieving
industry leading performance.
• I
supports partial Power-Down mode operation
OFF
• Drive Capability 16mA @ 2.5V
The PI74AUC164245 is a 16-bit (dual-octal) noninverting bus
transceiver that contains two separate supply rails. B port (V
)
CCB
• Each supply rail is configurable over supply range
set to operate at 0.8 to 2.5V and A port (V
) set to operate
CCA
• ESD Protection exceeds JESD22
– 2000V Human Body Model (A114-B)
– 200V Machine Model (A115-A)
at 0.8 to 2.5V. This arrangement permits universal bidirectional
translation over the voltage ranges.
The PI74AUC164245isdesignedforasynchronouscommunication
between data buses. Data is transmitted from theAbus to the B bus
or vice versa, depending on the logic level at the direction control
(DIR)input.Theoutput-enable(OE)inputisusedtodisableoutputs
so buses are isolated.
• Latch-up performance exceeds 100mA per JESD 78
• Industrial operation at –40°C to +85°C
• Packaging:
– 48-pin plastic 240-mil TSSOP (A)
– 48-pin plastic 173-mil TVSOP (K)
The control pins, DIR, DIR, OE and OE are supplied by

The device is fully specified for partial-power-down applications
using I . The I circuitry disables the outputs, preventing
OFF
OFF
damaging current backflow through the device when it is powered
down.
Block Diagram
To ensure the high impedance state during power up or power

CC
a pullup resistor, the minimum value of the resistor is determined
by the current-sinking capability of the driver.

Note:
1. The input negative voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. This value is limited to 3.6V max.
3. The package thermal impedance is calculated in accordance with JESD 51.
4. Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

2. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
3. All input pulses are supplied by generators having the following characteristics: PRR ≤ 10Mz, ZO = 50Ω, Slow rate ≥ 1V/ns.
4. The outputs are measured one at a time with one transition per measurement.
